To all whom it may coiz'oem: v

Be it known that I, CABLL Beam, a subject of the Emperor of Germany, residin in the city and county of San Francisco as State of California, have invented new and useful Improvements in Oil-Burner Tips, of which the following is a specification.

This invention relates to oil burners and particularly to an improved tip for oil burners. i

The object of the present invention is to provide a simple, efficient tip for oil burners embodying details of construction and design rendering a single tip capable of producing flames of various size; and to provide a tip for oil burners, the flame of combustion of the gases being generated close to the orifice of the tip.

The invention consists of the parts, and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a perspective view of aburner tip. Fig. 2' is a side elevation of the burner Fig. 3 is a sectional view transversely Fig. 4 is a detail view of the tip having an orifice of different design from Fig. 2.

It is the desideratum to provide a burner tip attachable to various forms of burner structures one of which is indicated in Fig. 2 at 2; such tip being capable of generating a small or a large flame with equal efliciency. Many burners and tips as at present devised and used, result when in operation,'in the generation of a blaze which is in a position considerably distant, varying in different conditions, from the immediate mouth of the tip of the burner, and it is to provide a burner tip which will generate a flame in closer proximity to the tip orifice that I have provided a tip as indicated at 3, which has an internal thread 4 for the reception of a supply pipe or burner body, the forward end of the tip being substantially hemispher- 3, is provided with a frusto-conical chamber, 6, the forward and smaller end of which intersects the base of a slit, 8, formed in the outer end of the burner and, in the form of burner shown in Fig. 3, there is a cylindrical extension, 9, of the forward end of the chamber, the diameter of this extension being in excess of the width of the slitted forward portion of the burner whereby a transverse wall, 7 is formed in front of but adjacent the base of the slit where it intersects the forward end of the conical ch mber. It will thus e seen that the elitn'de portion, 9 of the amber permits the combustible gases to advance well toward the outer end of the tip and results in the spread of the flame, as indicated in Fig. 3, during combustion.

I have found by actually constructing and using the present burner under varying conditions, such for instance as under boilers of considerable horsepower, and also employing the same burner in a small household stove, that various forms and sizes of flames can be generated by the combustible issuing from the tip.

When an extremely narrow or tongue-like flame is desired for certain conditions of operation, as in Fig. 4, I omit the cylindrical portion 9 from the chamber 6', and cause the orifice slit or discharge mouth 8' to intersect with the plane of the wall 7, as indicated in Fig. 4.

One of the important objects of the present invention is to so design and construct the burner tip that the flame of combustion of the issuing mixture will take position relatively close to the end 5 of the tip and this I accomplish by forming upon or attaching to the burner tip a wind shield 10, H

. stove. as in Fig. 2, the induced drafts coming through the orifice of the stove or furnace, may flow around the shield 10, but this acts to prevent the draft from drawing directly against the flame of combustion, thereby permitting this flame to creep toward or generate closer to the actual discharge orifice of the tip. This will be better understood by stating that if the wind shield 10 is not employed, 'then the induced air draft rushes along the surface of the tip 3 and will occasionally extinguish the flame of combustion, particularly if the burner is being utilized with fluids under low pressure.

Having thus described my invention what I claim and desire to secure by Letters Patent is An improved burner tip having an internal chamber of frusto-conical form, said ti having a forward end provided with a slit which extends inwardly and has its inner end or base intersectin with and terminating at the forward an smaller end of the chamber, said chamber having a cylindrical portion about equal to the diameter of the smaller end of the chamber and for an extension thereof, the diameter of saig cylindrical extension being less than the width of the slit, whereby a transverse wall isformed in advance of the base of the slit, said wall projecting acres the ath of the fuel delivered through the cham er.

In testimony whereof I have hereunto set 15 my hand in the presence of two subscribing witnesses.
